Question
Complete the following passage with the items that would make the statements correct.
Our knowledge of the concepts surrounding the __(1)___ would not have surfaced were it not for the _(2)__ proposed by Alfred
Wegener in the early 1900s. But despite the early pieces of evidence from his work, it wasn't until much later that the idea of moving
continents could be validated by various features observed on the seafloor.
Through extensive seafloor mapping, it was discovered that there are __(3)___ that run roughly parallel to continental coastlines.
Studies in __(4)__ further made it clear that these are sites of_(5)__, and it is through this process that oceanic crust is__(6)__.
Aside from that, there are also regions of linear depressions called __(7)__, marking the deepest portions of the Earth's crust. These
are places along which crustal __(8)___ takes place and oceanic crust is__(9)___.
The discoveries from these two features have had profound implications on our understanding of the geodynamic Earth. This
phenomenon also explains why there tends to be a huge discrepancy between the __(10)___ of continental and oceanic crusts.
